Free/Busy in Outlook only shows some calendar items, not all

I've gotten the Outlook Connector to work, and I've configured it so I can see the free/busy times of my co-workers, but the only free/busy times of theirs I can see are those of calendar items I have invited them to. If they add something to their own calendars, it doesn't show up when I view their free/busy times. This all works fine in the Zimbra online client; I can see the free/busy times of all their calendar items. It's just in Outlook where I can't. Is this a bug? Is there any fix?

because my account name (temporary, in this case) is charlie@hardtorememberurl.com. What seems to be happening is that when I'm scheduling an event in Outlook and add nick@hardtorememberurl.com as an attendee, it goes to the above URL to look for his free/busy info. The problem is that because my account is specified in the URL, it only returns MY free/busy info! What URL should I use to get everyone's free/busy info instead of just mine? I tried taking the ?acct=charlie@hardtorememberurl.com off of the end, but it gave me an error.

Cannot see free busy info in Outlook

I have installed the outlook connector. I can download send and receive email.
I can find all the users in the Global Address Book. I cannot see their calendars in Outlook.
I can see their calendars in the web client. I can scedual appointments in the webcliend and they show up in Outlook.

I receive a popup alert box from Outlook with this message
" Unable to display the folder. Your profile is not configured to support this operation for this user."

I am running the ZCS network addition 3.0.1_GA_160.RHEL4 on Fedora core 4
